Subject [jira] [Commented] (YARN-4356) ensure the timeline service v.2 is disabled cleanly and has no impact when it's turned off
Date Tue, 05 Jan 2016 22:54:39 GMT

    [ https://issues.apache.org/jira/browse/YARN-4356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15083994#comment-15083994

Vrushali C commented on YARN-4356:
----------------------------------

Yes, if we want the behavior to be different. If the 2.1 behavior simply builds upon 2, then
we can leave it as TimelineV2. Or if you'd like, we can have a simple addendum patch to make
it clearer, as you had suggested.

> For us to be able to merge the first milestone drop to trunk, we want to ensure that
once disabled the timeline service v.2 has no impact from the server side to the client side.
If the timeline service is not enabled, no action should be done. If v.1 is enabled but not
v.2, v.1 should behave the same as it does before the merge.
